One of the most noticeable differences between premium and low-cost cars is noise levels. If, after riding in the first one, immediately ride in the second, difference is obvious. Moreover, if the noise and hum can still be endured for a few minutes, then with frequent using of the car and when traveling long distances, the noise turns into an annoying factor number 1. The sources of noise are, as well, as inside the car - this is the creak of cheap plastic, and rattling elements, and engine. So outside - sounds from the wings, trunk, antenna and tires. Loud noise turns into a real problem, especially when you need to chat with passengers or listen to music.
Only soundproofing helps you here. Special materials are applied to certain areas of the car body - vibro-deadening and sound absorbing. Their main functions are:
- absorption of sounds and damping of vibrations created by plastic parts;
- protection of the interior from the noise of friction of tires on the road surface and from the hum of the engine.
How to increase noise and vibro insulation of the car?
The first stage in the application of soundproofing materials is the dismantling of the car interior to metal. The surface of the metal must be checked for corrosive processes, because it is necessary to get rid of such spots before installing the soundproofing. Otherwise, after installing the materials, even a small speck will continue to grow, and in order to remove it, you will then have to peel materials off. You definitely need to cover the metal on the doors, floor, engine compartment, trunk and fender arches - this is painstaking work. Often the ceiling is glued with soundproofing.
The installation of soundproof materials can be divided into 2 stages - installation of vibro dampers and installation of noise absorbers. You can mount them yourself. First, calculate the amount of materials for soundproofing. The brand that makes great materials is Smartmat. Soundproofing materials Smartmat does an excellent job of protecting against vibration and external noise. Pay special attention to characteristics such as thickness and weight, otherwise the door hinges may not be able to withstand the increased weight of the doors, and the trim elements will not be able to return to their previous positions.
For easy installation, many materials have a moisture-resistant self-adhesive layer. Another stage of work that allows the materials to securely attach to the surface is surface degreasing. Then cut the materials into pieces of the desired shape and size. To install some materials, they must be preheated with heat gun.
Is it better to install sound deadening materials yourself or contact a specialist?
Self0made work may take more than one day. If you do not have the required amount of free time, then it is better to apply for this service to a specialized service, trusting its employees. Moreover, if you decide to do it yourself, then remember the main mistakes of beginners. For example, when only sound-absorbing materials are glued to the metal, "forgetting" about vibro damper, there are still unnecessary sounds in the cabin. It is also worth considering that if only the doors are processed with the help of materials, then the result will be minimal, since extraneous noise will penetrate through the trunk, ceiling, wheel arches, hood, etc.
Do not be afraid to spend time and effort on really high-quality comprehensive sound and vibro deadening - as a reward, you will receive coziness and a comfortable atmosphere in the car. From pleasant communication with fellow travelers or from the wonderful music during the trip, no extraneous noise will distract you.
